Display touch control method and control system based on laser radar

The invention relates to the technical field of G06F3, in particular to a display touch control method and system based on a laser radar. A display touch control method based on a laser radar comprises the following steps: through mutual connection of the laser radar, a local computer and a display screen, performing touch action and position in a display screen area, obtaining position information through the laser radar, and scanning through a sensor on the laser radar to obtain the position angle and distance of the touch action; obtaining two-dimensional point cloud position information, establishing a polar coordinate system, converting the polar coordinate system into a two-dimensional XY coordinate system, converting the two-dimensional XY coordinate system into an XY coordinate system of a display screen vertex through a relative position difference between the screen vertex and the laser radar, and acting a touch action on a display screen area through interactive logic judgment; according to the tec
